To all whom it may concern:

Be it known that 'I, HARRY GRAY, a sub.- ject of the King of Great Britain, residing at 1 Railway Terrace, Rawtenstall, in :the countyof Lancaster, England, have invent ed :new and useful Improvements-in Machines for Beetling Fabrics, of whichthe following is-a specification. 1

My invention relates to improvements machines for beetling fabrics the object of my invention being to expedite the operation and to save labor.

'In .carryingym-y invention into effect Idispense with the ordinary 'fallers and in their place I employ 'a number of air, .oriother uid, cylinders, one pair. of cylindersfor each beetling block. Nearthe'top of the machine is mounted a shaft upon which is secured a number of 1 eccentrics whichactuateeonne-cting rods feach of which carries a piston fitted into one of the larger cylinders of each pair of cylinders and to each srnaller cylinder is fitted a piston to which is secured a heetling block. together and there is a passage for air between the cylinders and a non returny-valve. fittedover a small hole admits airto the -pas-' sage andcylinders at the proper time. The

cloth to be beetledis placed-preferablyupon two beams, one at each side of-the machine,

and the beetling blocks ac't preferably upon the cloth on the under side of the-beams.

In the accompanying four sheets of drawings Figure 1 is a front elevation, Fig. "2 an end elevation, and Fig. *a plan view of a beetling machine made according to my invention. Fig. 4 is a diagrammatic view, partly in section, of the shaft with eccentrics, fluid cylinders and pistons.

In these views:2 denotes the frame of the beetling machine 3 the batch rollers upon which the cloth to be beetled is wound; 4a shaft near the top of the machine; 5 a numbenof eccentrics secured upon this shaft; 6 a series of rods fitted upon the eccentrics; 7 pistons, one of which is connected to the end of each rod; 8 the fluid cylindersfor these pistons; 9 a series of fluid cylinders; these cylinders 8 and 9 are preferably cast to-.

Each pair of cylinders maybe cast cured upon each piston 12-; 14 an enlargement or air cushion chamber at the top of each cylinder 9; and 15 a projection upon each piston 12,wl1'-ich fits into its aircushion chamber 14 and so prevents injury when in work.

The shaft 4 is driven in any-convenient=mannersay bya belt and pulleys, not shown, and upon-one end of this shaft is secured a worm 16 which gears into a worm wheel 17 secured upon a shaft 18; a pulley 1-9 on :this shaft drives by a belt a pulley 20 secured upon a shaft 21, and a bevel wheel 22 on one end of this shaft gears into a similar wheel 23 secured upon a short shaft 24. A spur wheel 25 with a wide face, is secured upon the shaft 24and this wheel 25 gears with a-spur wheel 26 secured upon the shaft of one of the batch rollers 3. The-other -batch roller 3 is driven fromtheshaft'2l by a similar-train of gearing to which the same reference nu merals are applied.

The motion for reciprocating the batching rollers isonly shown a plied to one roller3, in Figs. 1 and3; but a like motion is applied to the other roller, and it consists of the shaft 21, upon which is secured a chain wheel 27, and a chain passes around this wheel and over a chain wheel 28 secured upona shaft 29 and turns the shaft. Aneccentric 30 upon this shaft fits into an'eccentricstrap upon a rod 31 formed with a forked end, projections on which enter a groove in a boss 32-secur ed :upon the shaft'of one :of the batch rollers. Similar mechanism, actuated by an eccentric upon the other end of the shaft 29, is employed to give a reciprocating motion to the other batch roller. When one roller travels to the right hand the other travels to the left and so balances the mech anism.

Breakage or damage when the beetling blocks return into their cylinders is prevented by the air cushion formed between the enlarged portions 15 of the pistons and the chambers 14 of the cylinders.

The operation is as follows :When the machine is set in motion the eccentrics 5 on the shaft 4 cause the connecting rods 6 to recipro'cate one after the other, and, as each piston 7 starts its inward journey, the air in its cylinder 8 is compressed and forced through the passage 10 into its adjoining rapidly upward thus causing the beetling block. 13 it carries to strike a quick and heavy blow upon the cloth. As soon as the first piston 7 reaches the end of its inward stroke and begins its outward movement, a little air is drawn through the check valve 11 into the passage and the cylinders and the piston with the beetling block is drawn rapidly downward by the partial vacuum caused in the cylinder 9 by the ascending piston 7. The batch rollers are turned slowly around and reciprocated by the mech anism described so long as the beetling is taking place.

To regulate the strength of the blow a weighted valve could be applied to the larger cylinders 8 to allow some air to escape as the pistons 7 descend.

When only one batch of cloth is being beetled I stop the movements of the blocks upon the other side of the machine by propping the non-return valves open in any convenient manner.

My improvements can be readily applied to the ordinary beetling machine, and to effect this I mount the eccentric shaft below the batch rollers, and employ only one row of beetling blocks, but two batch rollers, so that when the cloth upon one roller is being beetled, the beetled cloth upon the other can be unwound and another batch of cloth wound on ready to be brought into position for being bettled. The old beetling blocks can be used simultaneously or dispensed with.

I am aware that various arrangements have been previously proposed for working the hammers, beetles or fallers of beetling machines, by steam, air, or other fluid pressure, but in such arrangements the actuating pistons have usually all been controlled and operated from a single air compressor, steam cylinder, or other source of motive fiuid, although in one arrangement it has been proposed to divide the hammers, or fallers into two equal groups and to operate one half from one air compressor, and the remainder from a second compressor, so that half the hammers or fallers are up while the other half are down.

In my arrangement the essential feature of novelty consists in the use and application of a separate air compressor for each beet ling piston. Each air compressor consists ol a cylinder and a piston, the latter connected by a rod and strap to an eccentric or equivalent on a driven shalt, so that as the piston is driven inward it compresses and forces the air in the cylinder through a passage into a connected cylinder and thereby gives an effective stroke to the bectling piston therein.

It will be understood that in my arrange ment it is possible to have the bcctling pistons and blocks striking the cloth successively, simultaneously, or in any desired combination, whereas in the previous arrangements all the hammers must strike either simultaneously or half at one stroke and the remainder on the other stroke. Further by my arrangement it is possibleto put any desired number oi the beetling blocks out ol action by merely keeping its non-return valve open, and this is a distinct advantage when varying widths of cloth are being beetled.

Having now particularly described. and

ascertained the nature of my said invention and in what manner the same is to be per iormed I declare that what I clain'i is: A beetling machine comprising pairs of upright cylinders adapted to contain a suitable fluid, the bottoms of the cylinders olf each pair being connected together by a passage, a driven piston in one cylinder of each pair, a driving piston in the other cylinder adapted to act upon the fluid in the cylinders to move the driven piston, and means for actuating the driving pistons.

In testimony whereol' I have signed my name to this specification in the presence of two subscribing witnesses.
